Wow!! She sure is pretty :thumbup: !!!!
Try using some good quality sewing machine oil to clean her up. Just put some on with your fingers and then gently rub it around and let it sit for a few minutes, Using a soft cloth or cotton balls wipe off the oil and some of the dirt will come with it. You will probably have to do this more than once for each area. Do it to an area that won't show just in case something happens to the decals :shock: . I used sewing machine oil on mine and nothing happened.
I used "No. 7 Chrome & Metal Polish" (got it at the local hardware store) on the face plate of my new 201-2, the other day, and it really worked good. I put it on a cloth and rubbed the face plate the in same way I that rub silverware when I'm polishing the tarnish off. The face plate went from being brownish yellow to nice and shiny!!
